EEGENEEATOR.

`To allwhmn fit mag/concern.' I v Be it known that I, FRANCIS HoDGiiINsoN, a. subject of the King of Great Britain and Ireland, and a resident of Edgewood Park, .in the county of Allegheny ,and State of Pe'nnsylvani'm'have made anew and useful Invention in Regenerators, of which the foland heat is imparted to the liquid when 2o employed for intermingling or intimately.

the pressure builds vup in thc regenerator and the liquid is evaporated to Supply the demand for steam when the iii the regenerator.

An object of this invention, is to produce a regenerator in Whichsimple Ameans are pressure falls mixing the steam vand the liquid employed :1s-.a heatstoring agent. This and other objects I attain in a regenerator embodying the features herein described and illustrated.

ln the drawings accompanying this application and forming a part-thereof, Figure l is a sectional elevation of a iegeiierator embodying my invention; Fig. 2 is a partial sectional view of a portion of tlie apparatus shown in Fig. 1 and shows an alternative ar- "i'angei'ncnt for one yof the details of the apparatus, and Fiom` 3 is aii elevational view of a sliglitlymodied form of my invention The apparatus'disclosed as cnibodyingm i invention is adapted to periodically receive steam or tofreceivc varying amounts of iii entering the apparatus is brought into intimate contact with the heat storiii g liquid f v(preferably water) and is caused to 'carry the water with it4 as it traverses the pas- -sages of the apparatus. In addition to this of the apparatus.

the circulation of Water throughout the apparatus is accomplished by vmeans of varia` tions in steam pressure in the different paits Referring to the drawings, tlie regenerator consists of a receiving chamber 3, to

which steam is delivered, a delivery chamber. 4 from which steam is discharged and a water and steam circulatory system which connects the two chambers. For the sake Specification of Letters Patent.

-chamber 4 and with the top of the chamber lthe -chamber V4 and isso Situated 4that the The steam 4 Patented sept. a 1 m .r

of clea'rness Tihave shown' the' chamber 3 located below the chamber 4. It is obvious,

however, that the chamber 3 may be located lnormally below the water levelin the chainber 4.

The heat storing liquid, is delivered to the chamber 4 through a pipe 5 and is prevented from exceeding a predetermined level in thisA chamber by an overflow pipe 6." The delivery of Water lthrough the pi 3c 5 isusually controlled by a loat valve lnotshown) which maintains the water ata determined level in the chamber. A water delivery pipe-7 communicates with the bottom of the 3 and isadapted to be closed at its lower end by a valve 8 located in the chamber 3 -and provided with a closing ./v'veig'htfl).A .The valve 8 operates in response to variations of pressure lin the chamber 3 relative to the pressure-in the chamber 4.

A pipe l10 communicates with the chamber 3 near the bottom of the chamber and withl the chamber 4. A pipe 11 is located within 80 pipe 10' communicates through it with the" upper port-ion of the chamber 4. A steaml delivery ipe l2 communicates with the upper portion of the chamber 4 and vis separated from the pipe 11 by means of a bailleA plate or otlier`battling means 13. Steam is delivered to the chamber 3 through piping 14 which enters tlie upper portion of the `chamber and is preferably located on the Cppositezside -ofthc chamber lfrom the iiiletto`tlie`piping- 10. A check valve 15 is provided in the piping 14 and opens against the pressure in the chamber 3. 4A safety or blow off valve lf3-is mounted on the chamber 4 and communicates with the upper portion of thepchamber.

The opera-tion of the apparatus isl as fol-f v lows: When steam is admitted to the receiving Chamber 3 the" pressure in that chamber builds up unt-il itis sui'icient to lift the water contained in the chamber to the delivery chamber 4 through the piping 'l0 and 1l.

.The pressure iii the chamber 3 will be main-v tained at a pressure corresponding to` the weight of the column of water in the .piping 10 and 11 plus the pressure in tli`e chamber end of the pipe 11 so that the steam baille is so arranged that it '10 and 11, carries Water the steam has a freer passage "the pressure in 4 as long as the continuity of the column of Water in the piping 10 and 11 is maintained. lV hen the Water level in the chamber J is decreased to such an extent that the c'outinuityof the column of water in the piping 10 and 11 is broken, the pressure in the chamber 3 will drop, because the steam has a more `or less unrestricted passage through the piping 10 and 11i into the chainber 4. The steam in traversing the piping from the chamber 3 with it and delivers it to the chamber 4. 'lhe pressure in the chamber 3 drops as the water level in that chamber falls, because through the piping to the chamber 4. At some determined pressure in the chamber 3, relative tothe pressure in the chamber 4, the valve 8 is opened by the Weight of the column of water above it and the pressure in the chamber 4 and a stream ot' Water is,` delivered from the chamber 4 to the chamber 3. The amount of the valve opening is bdependent on the diderence in pressure between the chambers Sand 4 and will vary with the variations of pressure. As the pressure drops in the chamber 3, the valve will increase the flow of Water to that chamber, and as the pressure rises in the chamber 3 relative to the chamber 4 the valve Wil'l operate to decrease the HOW of Water. The result is that the amount of water carried by the' steam traversing the passages l() and 11, is proportioned to the flow of steam through the chamber 3.

The baille 13 is provided over the delivce'ry ischarged from the piping 12 is comparatively dry and is not mixed with the Water and Wet steam delivered by thepiping 11. This deflects the oW oi steam and Water downwardly into the body of Water 'contained in the chamber 4. A perforated branch pipe 17 communicates with the pipe 7 and is so arranged that Water delivered from the chamber 4 t0 the chamber 3 is taken from all parts of the body of Water contained in the chamber 4. In Fig. 2 I have shown the valve 8 provided. with an operating spring adapted to perform. the function of the Weight 9 shown in Fig. 1.
